Candido Luna, with his on Steven 18-months-old, and his wife Maria Meza, waits at Danbury Library for the start of an immigration reform rally which began with a march down Main Street, Tuesday, April 9, 2013.

The rally in Danbury echoed those in neighboring cities of New Haven, Stamford, Bridgeport and Hartford and elsewhere around the country. The "Time Is Now for Immigration Reform" movement also plans to rally on the west lawn of the U.S. Capitol on Wednesday.

Demonstrators said they are pushing for Congress to enact immigration reform legislation now, particularly a path to citizenship for 11 million undocumented immigrants now in the country.

State legislatures across the nation also have been getting involved in immigration issues, with lawmakers expressing frustration at inaction on what has long been viewed as a federal responsibility.

Around the country, 16 states, many with largest percentage of undocumented residents, have introduced or plan to introduce resolutions in support of immigration reform.

Nevada, New Jersey and New Mexico have resolutions that passed at least one chamber and other states that have introduced resolutions are Arizona, Florida, Georgia, Hawaii, Oklahoma, Oregon, and Texas, according to the non-partisan, nonprofit Progressive States Network.

Previously, in some states, such as Arizona, officials have sought to crack down on undocumented immigrants.

In Connecticut there are about 120,000 undocumented residents, which represents 3.4 percent of the state's population of 3.4 million, according to a 2010 study by the Pew center. Of those, 85,000 are in the labor force, which represents 4.5 percent of the state's labor pool of 1.8 million.

Of the U.S. total of undocumented immigrants, about 1.76 million are young adults and children, including 10,000 in Connecticut, who came to the United States as children.

Many may be eligible for President Barack Obama's deferred action initiative, which provides a minimum two-year reprieve from possible deportation.

In some cases, the deferred action initiative provides work authorization for those who meet the age, educational, residency, and other requirements. About 1.26 million meet the age criteria now.
